AA NiMH (Nickel Metal Hydride) are rechargeable batteries that are often used in consumer electronics, manufacturing and industry and in offices everywhere.

The strength of an NiMh AA battery is between two and three times stronger than the chemistry called Nickel Cadmium. This is abbreviated as NiCD, which are also rechargeable. They are very popularly used in high-drain (consuming a lot of power) devices like Digital Cameras, Flashes, Radios and Flash Lights, just to name some. In these products where a lot of power is required to operate them, it’s easy to understand why hi-power batteries are the ideal choice and mostly sought after cells.

One of the most beneficial features that NiMH battery chemistry offers, in all battery sizes, not only AA, is that they do not sustain what is known as MEMORY EFFECT, an effect which can be seen in NICD batteries.

What this translates to, is that they can be charged and recharged at any time, without concern for how much power they have left remaining in them. Memory effect is a result. It’s the result of charging a battery before it has become fully depleted of power. In a battery that can sustain memory effect, if it’s charged before being “dead”, it will only be topped off and this new level, (the point it was topped off from), will become the battery’s new total amount of power. Clearly this can drastically shorten the runtime of a battery. In NIMH technology, this effect doesn’t occur. It’s quite a freedom for many to charge and recharge NIMH batteries because don’t have to wait until those batteries have run out of power.

We mentioned run time. We’d like to explain what that is. Run time is simply the length of time (hours) that a cell will deliver power for, (over the span of one full charge).

AA NiMH batteries offer many life cycles of recharging. This is significantly higher than the single life span offered in Alkaline batteries, which are not rechargeable.

There is today, a more advanced battery chemistry in AA size, as well as many other sizes, that is available in NIMH chemistry. It’s called LSD or, in its unabbreviated form, Low Self Discharge. They hold, or retain their charge, much longer than standard or regular NIMH. They discharge (when not in use – idle) much more slowly than standard ones. They can actually hold about 85 percent of their power (charge) while just sitting on the shelf, over about a 2 year span! That’s extremely beneficial for institutions and other volume users of LSD batteries who’s inventory might remain on the shelf for extended periods of time, until needed. Schools, for example, close during the summer season. Upon reopening in the Autumn, their LSD stock is still as fresh as it was back in June when they closed. We sell a large quantity of LSD batteries to vocational and trade schools and universities.

Low Discharge batteries were first brought to market by Sanyo Corporation back in 2005. Since then of course, many other battery manufacturers have begun offering their own versions of low discharge batteries as well.

For all large volume users of AA NiMH rechargeable batteries, you can save good money by buying your inventory in bulk packaging. If you’re a reseller, you might need them in display cards for retail sale. No problem.

We supply AA size NiMh rechargeable batteries at wholesale pricing to those who purchase quantity lots. We welcome Government Agency, School and University, Library, Corporate and Industrial Purchase Orders and will work with you closely, to deliver exactly what you require, when you require it. We are fully stocked and can accommodate scheduled shipments over time, as some customers require them, while others, prefer to have their order subdivided to several satellite locations of their organization. However you need them, just tell us! We are dedicated to becoming your number one battery supplier and will work hard to make it happen! We’ll work closely with you to meet just what your needs are! That’s the MEGA difference!
